BL> Mine is red lined at 5500 too, but I've never had it over 5000.
 BL> The little 3l straight-six spins well, but there's no point.
 BL> The Holden V6 is supposed to bounce valves.

 BV> Where do they bounce to ? I've run it out to 175kph already and
 BV> it was just humming.

  I don't know if they're updated it, but the original Buick V6 engine
used push rods rather than an overhead cam. Push rod engines bounce
valves above 6000 rpm and they carry a lot of extra mass overhead on
the cam. You hear the engine rev out, and then is just seems to make
more noise without going any faster. I never rev my engines that high
anyway... even the Bellet that was red hot and span to 7,000 rpm.

 BL> IRS tends to wind up a bit on hairpins and bounce the inside
 BL> wheel... unless it's done right. That was the one thing I
 BL> noticed about the Skyline's solid axle and Watt's link - it's
 BL> better on hairpins.

 BV> I'll let you know when I've had a chance to check it out.

  IRS is much better, though. I never knew what axle tramp meant,
until I discovered it in the solid-axle Skyline. A solid axle hops;
the IRS wriggles, and keeps more of the wheels on the ground more of
the time.

Regards,
Bob
